Samsung Galaxy S III GT-I9305
I could send and receive text messages before and after few days I can no longer receive text messages but I can send them. Tested with 2 different phones with 2 different SIM cards but I didn't receive messages from either one.
I don't have any messaging related apps installed apart from Skype which I haven't launched after installation of it.
My Nexus 5 has been able to send and receive text messages perfectly fine for 6 months now but as of a day or two ago it has just hasn't been able to send or receive messages from any text messaging app.
I am with Amaysim (in Australia), my phone is running Android 4.4.4 and I have tried sending messages from Hangouts, EvolveSMS and TextSecure and none have worked.
